Title: Improvements in electric wave filters incorporating piezoelectric crystal elements
IPC: H03H9/10
Filed: 1947-08-07
Abstract: 631,772. Impedance networks. WESTERN ELECTRIC CO., Inc. Aug. 7, 1947, No. 21775. Convention date, March 30, 1943. [Class 40 (viii)] [Also in Group XL (c)] A piezo-electric filter comprising an AT cut quartz plate has electrodes arranged and connected as shown in Figs. 8 or 10. The Specification explains in detail with the aid of graphs that this arrangement will vibrate in an odd but not an even shear mode so that troublesome responses due to the coupling between even shear and odd flexural modes is minimized. Coupling between the odd shear and even flexural modes may in addition be minimized by spacing the electrodes from the ends of the plate and if necessary arranging further earthed electrodes in at least part of the resulting marginal portion to remove the piezo-electric stress from these portions. These earthed electrodes should, however, be narrow otherwise excitation of the even order shear mode will result. Fig. 12 shows one of each type of crystal element arranged in cascade in a narrow band filter comprising in addition, input and output low-pass half section impedance transforming networks L1, C1, and resistance pads 32, 33 for minimizing changes in response due to temperature variation. The capacitors C2 represent the self-capacitances of the element. With this arrangement spurious responses of each section are suppressed by the other. The first crystal has a resonance peak below the passband and the second crystal a resonance peak above the pass-band.

Phosphorus-containing iron-bearing material, particularly iron sponge, is continuously charged to an arc furnace to which slagging materials are also charged, the feeding rate of lime being increased during the charging so that the CaO/SiO 2  ratio of the slag rises whereby phosphorus is removed from the bath at a rate which is substantially constant and higher than the rate at which it is being added by the charge. The feedrates may be controlled or an oxygen lance employed so that the FeO concentration in the slag is between 6% and 24% and the bath temperature is between 2550 F. and 2850 F., the feedrate of the ferrous material preferably being so controlled that that temperature is maintained while power to the electrodes is maintained at or near the maximum. To produce a vigorous boil in the bath the sponge iron should contain a residual combined oxygen content of 0À1% to 1À75%. Slagforming materials are preferably added to the arc regions where turbulence is high; the slag may be tapped intermittently or continuously at a location remote therefrom.

Title: Improvements in or relating to the purification of hydrocarbons
IPC: C10G50/00
Filed: 1924-09-23
Abstract: 222,481. Gray, T. T. Sept. 26, 1923, [Convention date]. Mineral oils, purifying.-In purifying hydrocarbon vapours, which may be obtained by cracking, by passage through a catalyst such as fullers earth, boneblack, bauxite., kieselguhr, &c., the vapours are passed round the vessel containing the catalyst before being passed through it. Unsaturated compounds become polymerized to form liquid products which may be returned to the still or be treated to obtain lubricating oils. Vapours from a pressure still 5, in which pressures of 5-35 atmospheres may be maintained, pass by a pipe 6 to the base of a dephlegmator 7 containing a catalyst vessel 8 open at the top. The vapours heat the vessel 8 before passing downwards through the catalyst, and pass through a separating chamber 12 to a condenser 13. The liquid polymers which form on the catalyst pass downwards into the chamber 12 and are either returned to the still by a pipe 18 or pass away through a cooling coil 20. The catalyst vessel may be closed at the top and open at the bottom, the vapours in this case entering the dephlegmator at the top, and the polymers and reflux passing from the base back to the still. A solvent such as the condensate from the process may be passed through the catalyst to remove polymerized products. The Specification as open to inspection under Sect. 91 (3) (a) states also that the catalyst vessel may be heated by a steam jacket or be provided with a heat-insulating casing. This subject-matter does not appear in the Specification as accepted.

IPC: H01J31/50
Filed: 1964-05-29
Abstract: A glass plate having channels extending between its opposite faces, for use in an X-ray image intensifier (see Division Hl), is formed by fusing together a plurality of parallel glass tubes, each of which is coated internally with a glass enamel.  A 10 mm. diameter lead glass tube is sprayed externally with a low-melting point enamel, and then coated internally with a glass enamel consisting of the oxides of lead (50% by weight), boron (25%), and bismuth (25%). The enamel is prepared by grinding glass of this composition to a frit, and adding to a solution of nitrocellulose in amyl acetate binder, the tube being filled with this coating solution, and subsequently drained and dried, the binder being removed by heat before the tube is drawn down to 200 microns diameter, during which process the coating is fired. More than one coating may be applied and separately fired, before drawing, to give a final coating thickness of 10 microns.  Cut lengths of the drawn tube are fused together by heating at 600 DEG C., the resulting plate being heated in hydrogen at 340 DEG  C. for two hours to reduce the coating and render it partially conductive. It may be partially reoxidized, to attain a desired value of conductivity, by immersing the plate in nearly boiling water.

Abstract: 1,102,779. Recording and playback. WESTERN ELECTRIC CO. Inc. 27 May, 1965 [5 June, 1964], No. 22516/65. Heading G5R. [Also in Division G1] In an apparatus for analysing complex signals carried on a magnetic tape 101 (Fig. 1) a portion of the tape is fed from a reel 10 to a supply reel 21 via sensing head 12 and periodically stopped on the periphery of a drum 17 and repeatedly scanned, by a head rotating inside the drum. During each rotation at a particular stop, the output signal is modulated by a different frequency, the resulting beat frequency being filtered by a fixed frequency filter, to provide an output corresponding to a particular frequency in the spectrum of the original signal. The selected portion of tape is clamped under tension at each step, it being arranged that the operation of the tensioning system is delayed relative to the clamp at each stop. The tensioning and clamping system is released and the record advanced by a preselected interval after the portion has been analysed in order to select the next contiguous portion of the record. The outputs are successively recorded by a stylus 22 on a record 39 carried on a drum 23 rotated in synchronism with the rotating head. The amplitude of a mark on the record 39 corresponds to the signal amplitude at any particular frequency, the frequency corresponding to the position across the medium, while distance along the medium corresponds to time. A more detailed description of the operating system circuitry is given (see Division G1).
